RE: st: RE: Saveold option

Many thanks to Roger and Dave for their help. Roger's advice has been helpful and, most importantly, it worked! Ilaria

Dear Statalisters: I guessed the same thing about saveold, but then checked the help menu of Stata 9 and found

****************************** "saveold saves the dataset currently in memory on disk under the name filename in Stata 7 format.

"If you are using Stata 9 and want to save a file so that it may be read by someone using Stata 8, simply use the save command. Stata 8 and Stata 9 share the same dataset format." ******************************

I can't guess the reason for Ilaria's problem (SE to intercooled perhaps?), but she should surely be able to get round the problem by following Professor Newson's advice.
